Decoding

This dataset is longitudinal in nature, comprising data from school years (2007/2008-2010/2011) following students in grade 1 to grade 4. Measures were chosen to provide a wide array of both reading and writing measures, encompassing reading and writing skills at the word, sentence, and larger passage or text levels. Participants were tested on all measures once a year, approximately one year apart. Participants were first grade students in the fall of 2007 whose parents consented to participate in the longitudinal study.

This dataset contains all longitudinal data for the entirety of the WRRMP. This includes 10 waves worth of twin data, with extensive reading, math, behavioral, and environmental measures. Due to the twin nature of the data, data is presented as both long and wide, with each twin represented twice within the dataset.

This dataset contains information from the Florida Progress Monitoring and Reporting Network (PMRN) linked to the Florida Twin Project twins. Data within this set contains information related to progress monitoring reading data and end of year reading achievement testing, student demographics, and school and teacher clusters for the 2003/2004 to 2013/2014 school years.
